Explore the transformative results delivered by the STOREDGE project—paving the way for a more resilient, efficient, and sustainable energy future. Here are our key achievements:
A first-of-its-kind compact thermochemical energy storage prototype has been designed, built, and validated under laboratory conditions (TRL 4). It stores medium-temperature heat using calcium hydroxide and upgrades it to high-temperature output by manipulating water vapor pressure.
This system proves the feasibility of storing energy for days or even seasons with no thermal loss—empowering a wide range of industrial and power generation applications.
STOREDGE successfully demonstrated a novel technique for heat upgrading, increasing output temperatures far beyond input levels.
This capability enables the integration of medium-temperature heat sources—like solar thermal or industrial waste heat—into high-efficiency power cycles, such as supercritical systems.
The project identified and optimised structured metal hydroxides (mainly calcium hydroxide) to ensure safe, stable, and efficient energy storage.
The chosen material offers long lifespan, high thermal efficiency, environmental safety, and full recyclability—key for long-term scalability and commercial adoption.
STOREDGE validated the scalability of its system to hundreds of MWh and flexibility to meet both daily and seasonal energy demands.
This result confirms its potential to become a critical asset in decarbonising industrial heat and stabilising renewable energy supply.
The technology demonstrated zero toxicity, minimal environmental footprint, and full compliance with health and safety standards—setting a new benchmark in clean thermal energy solutions.
